WarWalking With The ESP8266
[Steve] needed a tool to diagnose and fix his friend’s and family’s WiFi. A laptop would do, but WiFi modules and tiny OLED displays are cheap now. His solution was to build a War Walker, a tiny handheld device that would listen in WiFi access points, return the signal strength, and monitor the 2.4GHz environment around him.
The War Walker didn’t appear out of a vacuum. It’s based on the WarCollar Dope Scope, a tiny, portable device consisting of an off-the-shelf Chinese OLED display, an ESP8266 module, and a PCB that can charge batteries, provide a serial port, and ties …read more
Impressive Pi System Controls Large Office
A pile of Raspberry Pis isn’t what would spring to mind for most people when building a system to control a large office, but most people aren’t [Kamil Górski]. He decided to use Pis to run the office of his company Monterail when they moved to a larger space. The system they built is one of the largest Pi installations we have seen, controlling the lights, TVs, speakers and door access. It can all be controlled through a web interface, so anyone on the network can turn the lights on or off, check if a room is occupied or send …read more
You Might Not Be Able To Read This
Early today, some party unleashed a massive DDoS attack against Dyn, a major DNS host. This led to a number of websites being completely inaccessible. DNS is the backbone of the Internet. It is the phone book that turns URLs into IP addresses. Without it, the Internet still works, but you won’t be able to find anything.
Over the past few months, security professionals have suggested — in as responsible terms as possible — that something big could happen. In early September [Bruce Schneier] wrote, Someone Is Learning How To Take Down The Internet. The implication of this very general …read more
Hajime, Yet Another IoT Botnet
Following on the heels of Mirai, a family of malware exploiting Internet of Things devices, [Sam Edwards] and [Ioannis Profetis] of Rapidity Networks have discovered a malicious Internet worm dubbed Hajime which targets Internet of Things devices.
Around the beginning of October, news of an IoT botnet came forward, turning IP webcams around the world into a DDoS machine. Rapidity Networks took an interest in this worm, and set out a few honeypots in the hopes of discovering what makes it tick.
Looking closely at the data, there was evidence of a second botnet that was significantly more sophisticated. Right …read more
Are Today’s Engineers Worse?
Today’s engineers are just as good as the ones that came before, but that should not be the case and there is massive room for improvement. Improvement that can be realized by looking for the best of the world to come and the one we left behind.
Survivorship bias is real. When we look at the accomplishments of the engineers that came before us we are forced to only look at the best examples. It first really occurred to me that this was real when I saw what I still consider to be the most atrocious piece of consumer oriented …read more
